There is plenty of information available about radiant heating, but I have not found much on radiant air conditioning. I have a 2000 sq ft 1950s brick rancher with hot water radiant heat and a gas boiler. My current forced air air conditioner needs to be replaced so I was wondering if it would be possible to use my current heating system as a radiant air conditioner? I have experimented by running cold water through the system and it works find as long as the outside temp is not over 85. I was thinking of adding some type of chiller, but the only ones I have found are either too big or too small.
I am new at this so I don't know if what I would like to do is feasible or not. Any help or suggestions would be appreciated.
